On a machine with a 5TB array I created a single partition via gpt and a
filesystem using the defaults from newfs.
All seemed well until I tried to fill the partition with data. With "only"
870GB or so used utilities started reporting the disk as full. Shortly (a
few hours) after the machine panic'd.
During this time I had been trying to copy file via nfs and rsync onto the
array. After several crashes I tried a simple "dd if=/dev/zero of=./file"
and after writing ~33GB the machine rebooted (the panic details below are
from this reboot)
Details follow:

Kernel is the default SMP kernel and sources are from 28th Nov 2004.
I assume a proper debug kernel with symbols would be more helpful, but I
just wanted to know if this was a known bug - or something I have done
wrong, first.
Other than that is there anything else I can provide to help find this bug?
Thanks
Henry
